Application filed Itovember 23,1922. Serial No. 602,795.

My invention relates toimprovements in voice mechanisms and more particularly to mechanisms adapted to emit sounds such as ma-ma or pa-pa, etc. The main ob ec t of the invention is to provide an arrangement which will more or less automatically: produce such sounds and which mechanism, is simple and efficient in operation and construction andone which is not likely to get outof order.

Further and more specific objects, features and advantages Wlll more clearly appear .from the detail description given below taken in connection with the accompanying draw- .passagewayl15 caus ng 't-hcreed to again ings whiclrform part of this specification.

carried thereby embodying my improvements I ebellows is compressed and forced out .1 througlrt-he reed pipe 13 with sufficient force 3 is a vertical section through avoice mecha-J-tocausc the reed to make thesounds inquesnism embodying my improvements in a moditied form. Flg. 1 1s avertrcal section of the same taken, at right anglesflto the section shown in Fig. 3. Fig. 5 is a transverse sec 7 7 that the member 17 11 11111101 8 by gravity tion taken on the line 55 of Fig. 41.

Referring toFigs. 1 and 2, 6 represents a cradle provided with suitable rocking supports 7 7. The cradle is provided in one end with a compartment 8 across which extends'a rod 9 rigidly fixed to the sides 10,- 10 of the cradle; Rigidly secured to the rod- 9 as byset screw 11 is ahead member 12 pro- 'videdwith a suitable reedpipe 13 having a reed 14. The reed pipe 13 extends to a passageway 15 in the head 12, passageway 15 2 opening to the outside atmosphere at 16. 17 represents another .hea'd member which is heavily weighted as by being made. of lead and adapted to slide bygravity along rod 9.-;

The members 12 and 17' are connected by flexible means 18 such as a flexible membrane; of rubberizedcloth so as to provide a belr "15: so as to open and close the same to the outside atmosphere. For this purpose the valve 19 is provided with two apertures 22 .and 23, the vformer-being relatively short and the latterrelatively long;

When the cradle is rocked over to the right asjviewed in Fig. 1, the weighted end member 17-will slide along the bar 9 tothe right putting: the air in the bellows under pressure and when the aperture 22 comes opposite the passageway 15,- the reed 14 willspeak utteringa short sound like ma, and asthe member 17' continues its travel to the right theaperture 23 will soon come opposite the like 11121.3 When the member 17 thus slides toward the rigid mcinberl8, the air in. the

tionwhen the apertures 22 and 23 come op- '=pf0Site the passageway 15 as above described.

when theapertures 22 and 23 are. not opposite. to the passageway 15. When the cradle isrocked-ba-ck' to .thcllctt as viewed in Fig. 1, the weighted head 17 will be thrown to its normal positionas shown in Figs. 1 and 2.

.It-willthus be seen that the valve 19 is adapted to successively'open the reed pipe .1 to the outside -11t-111ospl1e1'e upon a single movement oftheheadmembers toward one another, and the wholeoperation takesplace substantially: automatically by gravity actu 'ating- 'the weighted member 17. Since the member 17 slides on the rod 9. the two head members are movable relatively toward one another in successively parallel planes.

Reterring to Figs. 3, tand 5, in the modification there shown, 25 represents a suitable cylindrical container made outofcardboard or other suitable material. havin fixed therein a head 26 by means of screws 27. 28 r'epresents a reed pipe carried the head 26 and having operativcly related thereto a reed. 29. Reed pipe 28 opens into a passageway 30 in the head 26, the outer end of which passage 30 is adapted to be opened or closed to the outside atmosphere by means of a flat metal sliding valve 31. The upper end of the sliding valve 31 is rigidly fixed to a weighted head 32. The head members 26 or duration.

carried to the outslde atmosphere through the lower end of the valve member 31 slides.

The apparatus is adapted to be placed inside the trunk portion of a doll. When the doll is seated the valve member 31 is pushed upwardly carrying with it the weighted head 32 so that the parts assume the position shown in Figs. 3 and 4. When the doll is lifted the weight 32 drops by gravity carrying with it the valve member 31 and compressing the air in the bellows and when the aperture 34 comes opposite the passageway 30, air is forced out through the reed pipe causing the reed to speak and emit sound like ma and as the head 32 continues to be forced downward under the weight of head 32, the aperture 35 comes opposite the passageway 30 and causes the reed to again speak and utter the sound .ma but of long- The sounds thus emitted are the perforations in head 36.

It will be apparent from the above that the arrangements shown are extremely simple and eflicient in operation and construction and the parts are compactly arranged. The valve member is secured to one end of the bellows and slides with respect to the other so that the apparatus is not likely to get out of order.

Although I have described my improvements in great detail and with respect to preferred forms thereof I do not desire to be limited to such details or forms since many changes and. modifications may be made and the invention embodied in widely different forms without departing from the spirit and scope thereof in its broader aspects.

What I claim as new and desire to secure by Letters Patent is:

1. A sound device having in combination a cylindrical casing, a head fixed therein, a.

weighty head movable by gravity therein to form a compressible air chamber between said heads, a reed pipe carried by the fixed head, an opening through which the sound issues from the reed pipe, and a control member secured to said weighty movable head and .movable therewith and having a plurality of apertures therethrough adapted to move past said opening to control the issuance of sound from the reed pipe.

2. A sound device having a fixed head, a weighty head movable: by gravity toward and from the fixed head, a bellows connected between said heads, a sound reed carried by the fixed head and operated by the bellows, an opening through which the sound from the reed is adapted to issue, and a control member secured to said weighty movable head and movable therewith and having a plurality of apertures therethrough adapted to move past said opening to control the is suance of sound from the reed pipe.

A sound device having in combination a cylindrical casing, a head fixed therein, a

weighty head movable by gravity therein to form a compressible air chamber between said heads, a reed pipe carried by the fixed head, an opening through which the sound issues from the reed pipe, and a control member secured to said weighty movable head and movable therewith and having a plurality of apertures therethrough adapted to move past said opening to control the issuance of sound from the reed pipe, and said control member comprising a fiat strip passing through the compressible air chamber. 41. A sound device having a fixed head, weighty head movable by gravity toward and from the fixed head,-a bellows connected between said heads, a sound reed carried by the fixed head and operated by the bellows,

and opening through which. the sound from the reed is adapted to issue, anda control member secured to said weighty movable head and movable therewith and having a plurality of apertures therethrough adapted to move past said opening to control the issuance of sound from the reed pipe, and-said control member passing through the bellows.

In testimony whereof I have signed my name to this specification.
